barzillialloyd's instructables

hi, I have redrawn a much simpler circuit u can try on a breadboard and it works great. Just follow each connection as shown accurately . For the function of each component, all the resistors act to reduce current and lower the voltage levels to each component for it to have exactly the right amount of current or voltage it needs to work with. The transistors are amplifiers, it amplifiers the noise received and can also act as switching between the signals by its operation.LEDs lightBattery gives powerCapacitors acts as filter, and also blocks dc voltage.Hope that's helps..
